PSR-4 issue with Zorb\Promocodes\Promocode\Promocode class

[piotrknapik]

I'm getting this one from composer:

Class Zorb\Promocodes\Promocode\Promocode located in ./vendor/zgabievi/laravel-promocodes/src/Models/Promocode.php does not comply with psr-4 autoloading standard. Skipping.

For me adding a line in composer.json's autoload helped:

    "autoload": {
        "psr-4": {
            "App\\": "app/",
            "Database\\Seeders\\": "database/seeds/",
            "Database\\Factories\\": "database/factories/",
            "Zorb\\Promocodes\\Promocode\\": "vendor/zgabievi/laravel-promocodes/src/Models/"
        }
    },

...still I think lib should have it straight with PSR-4
